Answer:
1: (The arteries carry blood away from the heart; the veins carry it back to the heart.)
2: (In the systemic circulation, the left ventricle pumps oxygen-rich blood into the aorta.)
4: (Blood, which is low in oxygen, is collected in veins and travels to the right atrium and into the right ventricle.)
Explanation:
The blood circulatory system (cardiovascular system) delivers nutrients and oxygen to all cells in the body. It consists of the heart and the blood vessels running through the entire body. ... In the systemic circulation, the left ventricle pumps oxygen-rich blood into the main artery (aorta).
The arteries carry blood away from the heart; the veins carry it back to the heart. ... The blood travels from the main artery to larger and smaller arteries and into the capillary network. There the blood drops off oxygen, nutrients and other important substances and picks up carbon dioxide and waste products.
The inferior and superior vena cava bring oxygen-poor blood from the body into the right atrium. The pulmonary artery channels oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium.

In healthcare amenities like in nursing homes and hospitals, MRSA (methicillin-resistant Staphylococcus aureus) infection is one of the most common concern. These infections generally involve the skin, and the individuals who are healthy can also get infected with the condition.
In order to prevent MRSA infection, doctors, nurses, and other healthcare workers need to follow certain steps. These are as follows:
1. Carefully clean the hospital rooms and medical apparatuses.
2. Clean their hands with soap and water, or with an alcohol-based hand sanitizer prior and post caring for a patient.
3. Test some patients to observe if they exhibit MRSA on their skin. This is done by swabbing a cotton tip in the nostril or on the skin of the patient.
4. Use contact precautions, while caring for the patients with MRSA.
The answer is <span>xylem and phloem.
Xylem and phloem are the transport tissues of vascular plants. </span><span>Parenchyma and collenchyma are ground tissue, while pith and cortex are stem tissue.
</span><span>Xylem and phloem provide transportation of water, minerals, food, and nutrients. Xylem transport water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants.

No because plants can’t really move on their own but they are still living
