Iodine capture requires energy, thanks to the iodine pump, with the action of Na K ATPase, this process can be stopped by ouabain.
When suffering from heatstroke, the body temperature rises to 40.5-42oC. Symptoms are dizziness, light-headedness, hot and red skin, possible delirium, and unconsciousness
Anterior optic-anterior hypothalamus has many heat-sensitive neurons and a few cold-sensitive neurons
Radiant heat loss is heat loss in the form of infrared rays, of the electromagnetic wave type
All cellular, biochemical, and enzymatic reactions are temperature dependent. Therefore, optimal body temperature regulation is required for physiological activities in endothermic animals.
Substances from the plasma pass through the capillary wall by endothelial cell endocytosis, where they are then expelled into the interstitial fluid
ADH increases water reabsorption in the distal tubule and collecting duct. When blood Na+ is below 135 mEq/l, the posterior pituitary gland stops secreting ADH, causing a large amount of dilute urine to be excreted.
Dehydration usually occurs shortly before feeling thirsty. Children, the elderly, and people with dementia may not be aware of the sensation of thirst.
Water is the body's largest single component. Children have the highest percentage of water to body weight, 75%.
The liver synthesizes fatty acids from glaucid, Protide and from lipid degradation products, fatty acids are cyclically metabolized.
Between the liver cells and the endothelial cell layer of the sinuses, there is a space called the Disse space, this is where the lymphatic system in the liver originates.
Hormones are chemicals that are secreted by a group of cells or an endocrine gland into the bloodstream and carried by the blood to the cells.
In the function of the adrenal medulla, which is related to sympathetic activity, sympathetic stimulation also induces secretion of adrenal medullary hormones.
Effects on body development: acting on most body tissues, increasing the number and size of cells, increasing the size of internal organs.
Hypothalamic neurons secrete RH-releasing hormones and IRH-inhibiting hormones that inhibit or stimulate anterior pituitary activity.
The outer ear has the pinna and the outer ear canal. The pinna of the human ear has protrusions and concavities, which have the effect of receiving sound from all sides without turning like some animals.
To pass through the alveolar-capillary membrane, it must pass through the respiratory membrane, as discussed above, and through the red blood cell membrane.
The airway is a system of tubes, from the outside to the inside, including nose, throat, larynx, trachea, bronchi, and bronchi entering the lungs.
Located on the inside, shaped like a butterfly, forming an anterior, posterior, and lateral horn
The respiratory centres are bilaterally symmetrical groups of neurons and are scattered throughout the medulla oblongata and pons
Norepinephrine receptors of the sympathetic system are called noradrenergic receptors, and in addition to norepinephrine, these receptors also respond to epinephrine.
When pressing hard on the eyeball, it stimulates the V cord, the impulse enters the medulla oblongata to stimulate the X cord to slow the heartbeat.
The neuronal body has the function of feeding the neuron. In addition, the neuron body can be the source of nerve impulses and can also be the place to receive nerve impulses from other places to transmit to the neuron.
During the functioning of the nervous system, neurons play a very important role, the flow of information into and out of the nervous system.
To study the functional areas of the cerebral cortex, people divide the cortex in different ways
