Children need more calcium than adults because they are still growing and developing. Calcium is crucial for building strong bones and teeth, as well as for supporting the growth of tissues and organs. Adequate calcium intake during childhood can help prevent future issues like osteoporosis.
Air and water vapor enter and exit through the stomata, tiny pores found on the surface of leaves, stems, and other plant organs. These openings are surrounded by specialized cells that can open and close to regulate gas exchange and water loss.
The main mechanism that controls internal temperature in humans is the hypothalamus, a part of the brain that acts as the body's thermostat. It receives signals from temperature receptors in the skin and organs and adjusts processes like sweating or shivering to regulate body temperature around a set point. Additionally, other organs like the skin, blood vessels, and sweat glands play a role in thermoregulation through processes like vasoconstriction and vasodilation.
Organs in animals are composed of different tissues serving specific functions, while in plants, organs are structures with distinct roles such as roots, stems, and leaves. Animal organs are typically more complex and involved in a wide range of physiological processes, while plant organs are more specialized for functions like photosynthesis, nutrient absorption, and support. Both animals and plants rely on their organs to carry out essential life functions and sustain their overall health and survival.
The minor organs in the human body's system include the tonsils, appendix, spleen, gallbladder, and pancreas. These organs have specific functions that contribute to overall health and well-being but are not as critical as major organs like the heart, lungs, liver, and kidneys.
A person can die if they have serious kidney problems such as a kidney failure. Your kidneys help to regulate organs and remove excess fluids, toxins and waste.
The kidneys are the organs that directly regulate the concentration of water in the blood by filtering excess water and solutes from the blood to form urine. They also help maintain proper balance of electrolytes in the body by reabsorbing or excreting them as needed.
Toxicology Unit examines body fluids and organs for the presence of drugs and poisons.
Organs combine with tissues and fluids to form organisms.
The pancreas secrets enzymes and controls your bodies natural balance of insulin to maintain blood sugar. If it fails it can cause your internal organs to literally be dissolved by bodily fluids.
The organs do this by varying the relative resistance of their own arterioles.
Parathyroid hormone (PTH) acts on the bones, kidneys, and intestines to increase blood levels of calcium. It does this by promoting the release of calcium from bones, increasing reabsorption of calcium in the kidneys, and enhancing absorption of calcium in the intestines.

bones, kidneys, small intestines(The major target end organs for parathyroid hormone (PTH) action are the kidneys, skeletal system, and intestine.)
Eyes are sensory organs that provide vision, kidneys are vital organs that filter waste and regulate fluid balance in the body, and skin is the largest organ of the body that acts as a protective barrier and helps regulate body temperature.
