Brain stem is the part of the human brain that houses the most primitive functions such as the control of heart rate, respiration, and blood pressure.
<h3>What is brain stem?</h3>
It is a part of the brain that is located between the rest of the brain and the spinal cord.
It is responsible for carrying out the most basic nervous system tasks for our survival, such as the regulation and maintenance of the heart rate and the automatic control of respiration.
Therefore, we can conclude that the brain stem is the part of the human brain that houses the most primitive functions such as the control of heart rate, respiration, and blood pressure.

Answer: the factors that increase cardiac output include:
--> Nervous stimulation and
--> Hypertrophy of the heart.
Explanation:
Cardiac output can be defined as the quantity of blood pumped into the aorta each minute by the heart. This is also the quantity of blood that flows through the circulation. There are factors that can cause increased cardiac output or that can lead to a hypereffective heart. They are:
--> NERVOUS STIMULATION: The combination of sympathetic stimulation and parasympathetic inhibition does two things to increase the pumping effectiveness or cardiac output of the heart. These include:
• it greatly increase the heart rate from the normal level of 72 beats/mum up to 180 to 200 beats /mom.
• it increases the strength of heart contraction, which is called increased contractility to twice it's normal strength.
--> HYPERTROPHY OF THE HEART: A long term increased workload, but not so much excess load that it damages the heart, causes the heart muscle to increase in mass and contractile strength in the same way that heavy exercise causes skeletal muscles to hypertrophy. This effect of increased muscle mass of the heart, allows the heart to pump much greater than usual amounts of cardiac output.
Answer:
arcic tundra
Explanation:
Tundra has two types: arctic and alpine. The coldest one is the arctic one as it is located in the northern hemisphere. Its conditions are very cruel, very cold.
The temperatures of an arctic tundra can go from 10 to 20 degrees of Farenheight in the summer. In the winter, the temperatures can go to -50 degrees. Thundra biome is one of the coldest and the biggest on Earth. It is located in the Arctic circle, mostly.
Answer:
The primary organism consumer in the food web is an herbivore.
Explanation:
Answer:
Bone pain is associated with leukemia because large number of cancer cells are present in the bone marrow.
Explanation:
Leukemia may be defined as the cancer of blood cells. This cancer generally starts in the bone marrow and leads to uncontrolled division of the cell.
An individual suffering from leukemia may experience bone or joint pain. Bone pain is more common in lymphoblastic leukemia. The bone pain is mainly caused by the uncontrolled growth of cancer cell in the bone marrow.
