With low temperatures, vasoconstriction occurs, that is, the decrease in the diameter of blood vessels, thus limiting the amount of blood that reaches the brain.
<h3>How is the post op for aneurysm?</h3>
Pain medication will be given as needed. After 24 to 48 hours, patients are transferred to their room. Monitoring will continue as you increase your activity level. In a few days, you will be released from the hospital and given discharge instructions.
With this information, we can conclude that with low temperatures, vasoconstriction occurs, that is, the decrease in the diameter of blood vessels, thus limiting the amount of blood that reaches the brain.

Answer:
Explanation:
The larynx is the organ which is situated below the tract where the pharynx splits into the trachea and the esophagus. It is present in the vocal folds of the throat. It is responsible for manipulating the volume and pitch of the sound produce by the throat for speech. It other functions such as it protects the airway from choking, and it regulates the flow of air into the lungs.
Answer:
The answer to the question: What thoracic muscle is the prime mover of shoulder flexion, would be, A: Pectoralis minor.
Explanation:
The movement, and stability of the shoulder joint, and the arm itself, depends mostly on many muscles and tendons that keep it from coming apart with movement. While all of them work together to protect this joint and permit arm movement, some of them will aid in a certain type of movement, while others will antagonize these first. The important thing here is that as your joint moves, these muscles activate to ensure stability and movement. During flexion, which is literally the movement of bringing the arm closer to the body, there are several muscles that act as synergists, meaning, they act together to ensure correct movement and stability. One such muscle is the pectoralis minor, which arises from the ribs, and then inserts into the coracoid process of the scapula. In conjunction with other muscles, the pectoralis minor will be prime in shoulder flexion, and will be aided by others.
Answer:
High concentrations of vasoconstrictor substances will increase the peripheral resistance.
Explanation:
Vasoconstriction substances cause blood vessels to narrow their lumen. The more narrow lumens, harder it is for the blood to go through that vessel. The reason for this is because the resistance increased, meaning that the friction between the blood and the vessels' walls is higher.
When we talk about peripheral resistance, it means the sum of all individual resistance of the body blood vessels (all arteries, all capillaries, all veins).
Answer:
Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart.
As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.
• As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated. Note that oxygen-poor or CO2 containing blood goes through the pulmonary artery to the lungs where CO2 is exchanged for O2.
Left side of the heart (operating at the same time as the right side of the heart)
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart.
As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.
When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
As the ventricle contracts, oxygen-enriched blood leaves the heart through the aortic valve, into the aorta and to the arteries and eventually into veins to complete the blood circulation in your body.
