You would definitely underweight. The villi in your small intestines increase intestinal absorptive surface area approximately 30-fold and 600-fold respectively. This provides exceptionally efficient absorption of nutrients in the lumen. This increases the surface area for food to be absorbed. So if there were to be less villi you would underweight.
Answer:
Is there any context to this? Is there a short story or smary before the question?
Answer:
The major blood vessels connected to your heart are the aorta, the superior vena cava, the inferior vena cava, the pulmonary artery (which takes oxygen-poor blood from the heart to the lungs where it is oxygenated), the pulmonary veins (which bring oxygen-rich blood from the lungs to the heart), and the coronary.
Answer:
A. Arteriovenous malformations (AVMs).
Explanation:
AVMs are known as a genetic condition in which blood vessels are formed incorrectly in the brain or spine. As these vessels are malformed they could break, which can lead to bleeding into the brain.
Answer: True
Explanation:
Ischemia is the reduction in blood flow to a tissue resulting in decreased oxygen and nutrient supplies to the tissue which may lead to cell death if not reversed.
Risk factors to ischemia includes:
1. Vascular diseases
2. Trauma
3. High blood pressure
4. Tobacco
5. Physical inactivity
6. High cholesterol.
Ischemia can be acute or chronic depending on its course of action. Acute ischemia occurs when there is a sudden decrease in the flow of blood to a tissue while chronic ischemia occurs when there is a gradual decrease in blood flow to a tissue.
Ischemia can be reversible when blood flow to the tissue returns. When irreversible, it leads to cell death.
