Reabsorption: Being absorbed again. For example, the kidney selectively reabsorbs substances it has already secreted into the renal tubules, such as glucose, protein, and sodium. These reabsorbed substances are returned to the blood.
What resorption means?
Resorption is the breakdown and assimilation of old bone in the cycle of bone growth. The process of resorption (remodeling) involves the removal of hard bone tissue by osteoclasts followed by the laying down of new bone cells by osteoblasts.
What is the definition of absorption in science?
Absorption is a chemical or physical phenomenon in which the molecules, atoms and ions of the substance getting absorbed enters into the bulk phase (gas, liquid or solid) of the material in which it is taken up. Absorption is the condition in which something gets mixed or absorbed completely in another substance.
What is absorbed in the nephron?
The proximal nephron absorbs about two-thirds of filtered sodium, without dissociating salt and water absorption. The thick ascending limb absorbs 25% of filtered Na+, but no water. The distal nephron absorbs 10% of filtered Na+ in close relation with K+ and, to some extent, H+ secretion.
Is urea reabsorbed?
Urea is passively reabsorbed in the proximal tubule, but its route of transport is not clear.
Can you reabsorb urine?
To conserve water, the kidney can reduce its rate of urine production and the urinary bladder can reabsorb fluid.
Is tibial a word?
tib·i·a. 1. a. The inner and larger of the two bones of the lower human leg, extending from the knee to the ankle.
Does inhibit mean stop?
to restrain, hinder, arrest, or check (an action, impulse, etc.). to prohibit; forbid. Psychology. to consciously or unconsciously suppress or restrain (psychologically or sociologically unacceptable behavior). Chemistry. to decrease the rate of action of or stop (a chemical reaction).
What do osteoclasts do?
Osteoclasts are the cells that degrade bone to initiate normal bone remodeling and mediate bone loss in pathologic conditions by increasing their resorptive activity. They are derived from precursors in the myeloid/monocyte lineage that circulate in the blood after their formation in the bone marrow.
What is an example of absorption in science?
(chemistry) The process by which one substance, such as a solid or liquid, takes up another substance, such as a liquid or gas, through minute pores or spaces between its molecules. A paper towel takes up water, and water takes up carbon dioxide, by absorption.
What is absorption in simple words?
Absorption is a condition in which something takes in another substance. It is a physical or chemical phenomenon or process, in which atoms, molecules, or ions enter in the inner part (called bulk) of a gas, liquid, or solid material. This is a different process from adsorption.
How is absorption and transmission difference?
The main difference between absorbance and transmittance is that absorbance measures how much of an incident light is absorbed when it travels in a material while transmittance measures how much of the light is transmitted. … As light passes through a material, it is absorbed by molecules in the material.
Are erythrocytes reabsorbed?
Erythrocytes, together with plasma proteins are retained in the vascular space, hence they do not become part of the tubular filtrate and are not excreted as components of healthy urine.
What is absorbed in the Bowman’s capsule?
Bowman’s capsule encloses a cluster of microscopic blood vessels—capillaries—called the glomerulus, where wastes are filtered from the blood. …
Is creatinine reabsorbed?
Creatinine is a nonprotein nitrogenous substance derived from muscle creatine. Circulating levels vary with dietary intake of creatine and muscle mass. It distributes through all body water more slowly than urea. It is freely filtered through the glomeruli, not reabsorbed in the tubules, and excreted in urine.
Is glucose reabsorbed?
Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule. This reabsorption is effected by two sodium-dependent glucose cotransporter (SGLT) proteins.
Is water reabsorbed?
Water reabsorption is by osmosis through water channels in the membrane. These water channels consist of a family of proteins called aquaporin. At least seven different aquaporin isoforms are expressed in the kidney.
Does kidney reabsorb sugar?
Glucose Reabsorption In addition to their important role in gluconeogenesis, the kidneys contribute to glucose homeostasis by filtering and reabsorbing glucose. Under normal conditions, the kidneys retrieve as much glucose as possible, rendering the urine virtually glucose free.
Does holding your pee feel good?
While this practice may give women pleasure, it’s actually not a great idea in the long run, Brito told Healthline. “It is not healthy to hold your urine in to have an orgasm,” Brito said. … Holding in your pee may lead to urinary tract infections or kidney problems.”
How long is too long to hold your pee?
When you hold your pee for 10 hours or more, you may develop urinary retention, meaning the muscles in your bladder can’t relax and let you relieve yourself, even when you want to. In very rare cases, holding your pee can cause your bladder to burst.
Why is it hard to pee after holding it?
Bladder stretching In the long term, regularly holding in pee can cause the bladder to stretch. This may make it difficult or impossible for the bladder to contract and release pee normally.
What is your fibula?
The fibula, sometimes called the calf bone, is smaller than the tibia and runs beside it. The top end of the fibula is located below the knee joint but is not part of the joint itself. The lower end of the fibula forms the outer part of the ankle joint.
What is a Tibiae?
Tibia and fibula are the two long bones located in the lower leg. The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The tibia is much thicker than the fibula. It is the main weight-bearing bone of the two.
What does ulna mean?
: the bone on the little-finger side of the human forearm also : a corresponding part of the forelimb of vertebrates above fishes. Other Words from ulna Example Sentences Learn More About ulna.

What is an example of inhibition?
The definition of an inhibition is something that holds you back or restrains you from doing or thinking something. When you are concerned about your body and don’t want to wear a swimsuit or go to the beach, your concern is an example of your inhibition.

What are bone marrows?
(bone MAYR-oh) The soft, spongy tissue that has many blood vessels and is found in the center of most bones. There are two types of bone marrow: red and yellow. Red bone marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets.
What causes osteopetrosis?
The X-linked type of osteopetrosis, OL-EDA-ID, results from mutations in the IKBKG gene. In about 30 percent of all cases of osteopetrosis, the cause of the condition is unknown. The genes associated with osteopetrosis are involved in the formation, development, and function of specialized cells called osteoclasts.
What is bone breakdown?
Bone resorption is resorption of bone tissue, that is, the process by which osteoclasts break down the tissue in bones and release the minerals, resulting in a transfer of calcium from bone tissue to the blood. The osteoclasts are multi-nucleated cells that contain numerous mitochondria and lysosomes.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
