A. Answer the following questions.
If solid and liquid wastes are removed by the body through defecation and urination, what is released by the body during respiration?
During respiration, the body releases carbon dioxide and water vapor as waste products. When we inhale, our lungs take in oxygen which is then used by our cells for various bodily functions. The byproduct of these processes is carbon dioxide, which is expelled from the body when we exhale.
What will happen if the blood vessel in the body is blocked?
If a blood vessel in the body is blocked, it can restrict or completely stop the flow of blood to certain areas of the body. This can lead to a range of serious health problems, depending on where the blockage occurs. For example, if a blockage happens in a coronary artery, it can cause a heart attack. In the brain, it can result in a stroke. Both of these conditions are medical emergencies and require immediate treatment.
How can you take care of your respiratory and circulatory systems?
Taking care of your respiratory and circulatory systems involves a few key practices:
Exercise regularly: Engaging in activities like walking, running, or swimming can strengthen your heart and improve lung capacity.
Eat a balanced diet: Consuming a variety of fruits, vegetables, whole grains, and lean proteins can support overall cardiovascular health.
Avoid smoking and limit exposure to pollutants: Smoking damages lung tissue and increases the risk of chronic respiratory diseases.
Stay hydrated: Drinking adequate amounts of water helps maintain blood volume and pressure.
Practice good hygiene: Regular handwashing and avoiding close contact with sick individuals can prevent respiratory infections.
B. Trace the pathway of blood as it circulates our body starting from our lungs.
From the Lungs, the pathway of blood circulation is as follows:
Lungs : Blood is oxygenated in the lungs.
Left Atrium : Oxygen-rich blood moves from the lungs to the left atrium of the heart via pulmonary veins.
Left Ventricle : Blood flows from the left atrium to the left ventricle.
Arteries : The left ventricle pumps the blood into the aorta, which distributes it to the body through various arteries.
Capillaries : Within the tissues, blood moves through capillaries where oxygen and nutrients are exchanged for carbon dioxide and waste.
Veins : The deoxygenated blood then returns to the heart through veins.
Right Atrium : Blood from the body returns to the right atrium.
Right Ventricle : It moves from the right atrium to the right ventricle.
Back to Lungs : Finally, the right ventricle pumps the blood to the lungs for oxygenation via the pulmonary arteries, and the cycle repeats.
