Answer:
The correct answer is a. greater than
Explanation:
The partial pressure of oxygen in alveolus is greater than partial pressure of oxygen in deoxygenated blood in a pulmonary capillary and this concentration difference is important for the movement of air(oxygen) from the alveolus to the pulmonary capillary because gases move from higher concentration to lower concentration.
By this process the oxygenated blood reaches to the heart from lungs and heart then pump this oxygenated blood to other body tissues.The partial pressure of oxygen in alveolus is 104 mmHg and in venus blood is 40 mmHg.

Answer: D. Contractility of the heart muscle refers to the force of contraction that this muscle can exert.
Explanation:
The myocardial contractility is ability of the heart muscles to contract. This is achieved by the forces which develop between the contracting muscles caused by the filaments of actin and myosin.
The degree of binding of the muscle filaments dependents upon the calcium ion concentration. These actions are controlled in vivo by the sympathetic nervous system. It is driven by the release of the catecholamine, which is a process which determines the calcium ion concentration inside the cytosol of the muscles of the heart.
Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
patient with iron deficiency anemia will have low hemoglobin levels as well as microcytic and hypochromic RBCs, according to the results of a complete blood count. Typically, the reticulocyte count is normal or slightly increased.
<h3>what is
iron deficiency anemia?</h3>
- Insufficient iron is the cause of iron deficiency anemia.
- Your body needs iron to produce enough of a component in red blood cells that makes it possible for them to carry oxygen (hemoglobin).
- Thus, iron deficiency anemia may make you feel lethargic and breathless.
<h3>How serious is iron deficiency anemia?</h3>
- Iron-deficiency anemia can have major side effects, including fatigue, headaches, restless legs syndrome, heart issues, problems during pregnancy, and delays in a child's development.
- Additionally, iron deficiency anemia can worsen other chronic illnesses or render their therapies ineffective.
<h3>What three levels of iron deficiency are there?</h3>
Deficiency in Iron Has 3 Stages
- Stage 1: A decrease in the body's overall iron content. A decrease in serum ferritin serves as an indicator of this stage.
- Stage 2 Reduced red blood cell production. This stage develops when there is not enough iron available to sustain the production of red blood cells.
- Stage 3 Iron deficiency anemia.
