Why does venous return from the distal arm travels in the superficial veins and those veins tend to bulge superficially in a person who is working out?
Blood distribution is adjusted by a short-term neural control mechanism to meet specific demands. During working out, the hypothalamus signals for reduced vasomotor stimulation of the skin vessels. Blood moves into the capillary veins, and heat radiates from the skin to reduce body temperature.
VeinsAll over your body, veins are blood vessels that collect blood with low oxygen content and send it back to your heart. Your circulatory system includes your veins. They cooperate with your heart, other blood vessels, and other organs to maintain blood flow. Most of your body's blood is stored in veins. Your veins actually contain around 75% of your blood. Veins have two basic functions. One function is to gather blood that is low in oxygen throughout your body and transport it back to your heart. The other function is to transport blood that is rich in oxygen from your lungs to your heart. Only during this process do veins transport oxygen-rich blood.

The anterior pituitary receives hypothalamic input through the portal blood supply. what is the advantage of this type of anatomical relationship?
The advantage of this type of anatomical relationship is that this enables the pituitary to receive signals before sending hormones to the rest of the body through the blood.
The anterior pituitary, a significant component of the endocrine system, is the glandular anterior lobe that, along with the posterior lobe (also known as the posterior pituitary or neurohypophysis), constitutes the pituitary gland (hypophysis).
Stress, growth, reproduction, and lactation are just a few of the physiological activities that the anterior pituitary controls.
Blood tests that assess hormone levels are frequently used to determine if the anterior pituitary and the organs it controls are functioning properly.
The hypothalamus-hypophyseal portal veins deliver hypothalamic releasing and inhibitory hormones directly to the anterior pituitary gland.
Certain hormones from the hypothalamus bind to receptors on particular anterior pituitary cells, controlling how much of the hormone they generate is released.

What factors would change during a pregnancy if the hormone progesterone were reduced or withdrawn?
If the hormone progesterone were reduced or withdrawn the uterus would contract more and peristalsis would increase.
Progesterone levels are generally high during pregnancy. The changes in progesterone cause a laxity or loosening of ligaments and joints throughout the body. In addition, high levels of progesterone cause internal structures to increase in size, such as the ureters. In normal pregnancies, at about seven weeks the placenta will make all the progesterone needed for a woman to stay pregnant. Progesterone plays an important role in the development of the fetus it also helps in growth of maternal breast tissue ,facilitate lactation, and strengthens the pelvic wall muscles in preparation for labor.

As electrons fall from photosystem ii to photosystem i, the cytochrome complex uses the energy to pump ions. this builds a proton gradient that is used in chemiosmosis to produce what molecule?
As electrons fall from photosystem ii to photosystem i, the cytochrome complex uses the energy to pump ions. this builds a proton gradient that is used in chemiosmosis to produce ATP.
In plants and cyanobacteria, a two-step mechanism known as noncyclic photophosphorylation results in the direct production of ATP and NADPH during photosynthesis. High-energy electrons exiting photosystem II are used in the noncyclic photophosphorylation process just outlined to produce ATP, which is then transferred to photosystem I to promote the creation of NADPH.
For every pair of electrons that move from H2O to NADP+ to create a molecule of NADPH, this results in the production of slightly more than one molecule of ATP.

What are the two major modes of glycolysis and what is the purpose of each mode?
The two major modes of glycolysis are aerobic and anaerobic glycolysis.
Glycolysis is the method by which glucose is broken down to produce energy. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
Both anaerobic and aerobic conditions can result in glycolysis.
Pyruvate enters the citric acid cycle under aerobic conditions and proceeds through oxidative phosphorylation, which results in the net synthesis of 32 ATP molecules. Pyruvate is converted to lactate in anaerobic conditions by anaerobic glycolysis. During anaerobic respiration, two ATP molecules are produced.
