What substances dissolve in blood eventually?
The main functions of blood is actually to transport dissolved substances, like hormones, around the body.The Plasma itself contains dissolved substances. Most of these are useful and are carried to places where they are to be stored or processed. The products of digestion including glucose, amino acids, mineral salts and vitamins are carried from the small intestines (ileum) to other organs. Glucose is either stored in the liver and muscles as glycogen or used in tissue respiration. Amino acids are used by all your tissues for growth and repair. The liver is able to remove excess amino acids from blood plasma and add some of those which are needed. The nitrogen from excess amino acids is turned into a harmful substance called urea.Vitamins are carried by plasma from the ileum to all other parts of the body. They help keep your tissues healthy. Minerals are also absorbed into blood plasma in the ileum and carried around the body. Different minerals are required for different reasons. You must know that calcium is needed for teeth and bones. It is also required for muscles. Calcium ions are involved in the chemical mechanisms of muscle contractions. So without enough calcium in your diet, your muscles are not able to contract correctly.Iodine is required by the thyroid gland in your neck to make a hormone called thyroxine. This controls how fast your body works. In particular, thyroxine affects the rate of tissue respiration. Hormones are secreted by endocrine glands and carried in blood plasma to target organs. Insulin is secreted by endocrine glands called “islets of Langerhans”. These are small groups of cells in your pancreas. The main target organ for insulin is the liver. Insulin stimulates the liver to convert excess glucose in your blood into glycogen. Insulin is also necessary for tissue respiration.The main baddies in your blood are urea and hydrogen carbonate ions. Urea is the product of excess amino acids. It is put into blood plasma by the liver and removed by the kidney. This process is called excretion. Your kidneys also excrete excess water and salts from your body. This process is called “osmoregulation”. It is under the control of the brain and involves chemical messengers ( hormones) secreted by the pituitary gland.Hydrogen carbonate ions are produced when carbon dioxide produced by tissue respiration is absorbed by blood plasma. In your lungs, hydrogen carbonate ions turn back to carbon dioxide which is excreted when you exhale.
Which cells carry oxygen to the muscle tissue?
B) Red blood cells carry oxygen to muscle tissue(erythrocytes)
How is Co2 carried away from the muscles?
As co2 is produced, it diffuses into the water that comprises most of the blood. The blood then carries the co2 to the lungs. Some of the co2 is also carried away by the lymph system.
How does Oxygen get to our muscles?
Haemoglobin molecules carry oxygen throughout the body to be used in a number of processes - respiration in particular. Oxygen enters the lungs, then is "picked up" by haemoglobin molecules in the blood within pulmonary veins. The pulmonary veins carry the blood back to the heart, where it is then pumped through the systemic system, via the Aorta (the artery that carrys oxygenated blood throughout the body). From the aorta, the oxygenated (or "red" blood, as it is sometimes known) enters the capillaries, where diffusion of oxygen and other substances occur. From here, the oxygen can be used in cellular respiration - in muscles, for example. The blood in the capillaries therefore loses all the oxygen it once carried, so is now referred to as "blue" blood. From the capillaries, it enters the Vena Cava (the vein that carries the deoxygenated blood back to the heart). From the heart, the blood is pumped back to the lungs, through the pulmonary artery - where the blood "picks up" yet more oxygen to repeat the process. I hope that made sense - remember than arteries carry blood AWAY from the heart, and veins carry blood TO the heart. (Hence, why veins appear blue) I hope this helped.
What is the oxygen carrying protein of muscle cells?
It's Myoglobin.It is a monomeric heme protein found mainly in muscle tissue where it serves as an intracellular storage site for oxygen.
What does blood transport away from the cells?
Carbon dioxide and other wastes. WHOA the second answerer is definitely going to win the voting.
Does nicotine inhibit muscular tissue from absorbing oxygen?
YES! Basically, what happens is that carbon monoxide adheres to red blood cells better than carbon dioxide and oxygen, so when you smoke, your red blood cells dont carry the oxygen around as well as a non-smoker. Red blood cells are what carries oxygen around and removes any toxins from muscles and what have you.
Help on blood vessel question?
*Why do their wall thicknesses differ? Arteries and veins are similar in their structures, but the arteries are composed of more muscular tissue than the veins are. This is because the arteries are transporting blood away from the heart, therefore they deal with high blood pressure flow. The veins are transporting blood toward the heart, therefore deal with low blood pressure flow. *How does the speed of blood flow differ in the three types of vessels? Arteries; high blood pressure/speed flow because it is taking blood away. Veins; low blood pressure/speed flow because it is taking blood toward the heart. Capillaries; these just connect veins and arteries together so the blood 'speed' is neither low or high, really. *How does this relate to their function? Well arteries take blood away from the heart, therefore are composed of thick muscular walls that help it to deal with the high blood pressure. Veins take blood toward the heart, and deal with low blood pressure. Although they may have a similar structure to arteries, they consist of less muscular walls/muscle tissue because of the low blood speed. Also, because it is carrying deoxygenated blood toward the heart, it is essential that the blood doesn't flow backwards; there are valves in the veins that prevent this. Capillaries simply join the arteries and veins. They are very thin blood vessels that transport nutrients to cells and also remove waste products. Hope that helped! :]
