Pertanyaan Seputar Darah Vena

Anemia is the correct answer because it refers to a disorder in the circulatory system caused by a decrease in the level of hemoglobin (Hb) or the number of red blood cells in the blood. Anemia can result from various factors such as iron deficiency, vitamin B12 deficiency, or chronic diseases. It leads to reduced oxygen-carrying capacity in the blood, causing symptoms like fatigue, weakness, and paleness. Unlike the other options mentioned, anemia specifically relates to a decrease in Hb or red blood cells, making it the most suitable answer.

The correct answer is "Eritropoesis." Eritropoesis refers to the process of red blood cell formation. It occurs in the bone marrow and involves the differentiation and maturation of erythrocyte progenitor cells into mature red blood cells. Eritropoesis is regulated by the hormone erythropoietin, which stimulates the production of red blood cells in response to low oxygen levels in the body.

Serum adalah cairan berwarna kuning putih yang mengandung antibodi untuk melawan zat atau benda yang masuk ke tubuh. Serum tidak mengandung sel-sel darah, seperti leukosit, eritrosit, trombosit, atau limfosit. Oleh karena itu, serum adalah jawaban yang tepat.

The correct answer is Arteri pulmonalis. The arteries carry oxygenated blood away from the heart to the rest of the body, while the veins carry deoxygenated blood back to the heart. The pulmonary artery is the only artery in the body that carries deoxygenated blood. Therefore, it is the artery that contains the highest concentration of CO2.

Hemofilia is a hereditary disorder that affects the blood's ability to clot. It is caused by a deficiency or absence of certain clotting factors in the blood. This condition is passed down from parents to their children through their genes, making it a genetic or hereditary disease. Hemofilia is not acquired or caused by external factors, but rather is present from birth due to a genetic mutation. Therefore, it is considered a hereditary or genetic disease.

Golongan darah O is considered the universal donor because it lacks the A and B antigens on its red blood cells. This means that individuals with other blood types can receive blood transfusions from donors with blood type O without the risk of an immune response. On the other hand, individuals with blood type O can only receive blood from other type O donors. Therefore, golongan darah O is the most compatible and widely used for blood transfusions in emergency situations when the recipient's blood type is unknown.

The vena pulmonalis is responsible for carrying oxygenated blood from the lungs to the left atrium of the heart. This is the correct answer because it accurately identifies the blood vessel that performs this specific function. The other options, such as the artery, capillary, vena kava superior, and vena kava inferior, do not carry oxygenated blood from the lungs to the heart.

Heparin is a substance that prevents the conversion of prothrombin into thrombin. It acts as an anticoagulant by inhibiting the activity of thrombin, which is necessary for blood clot formation. This prevents the formation of blood clots and helps to prevent excessive clotting within the blood vessels.

Kapiler adalah pembuluh darah yang bertugas mengalihkan darah menuju atau dari sel-sel tubuh dan berhubungan langsung dengan sel tubuh. Vena dan arteri adalah pembuluh darah yang mengalirkan darah dari dan ke jantung, sedangkan pembuluh balik adalah pembuluh darah yang mengalirkan darah dari organ-organ kecil kembali ke jantung. Nadi adalah getaran yang dirasakan ketika darah mengalir melalui arteri.

Golongan darah AB tidak memiliki aglutinin karena golongan darah AB memiliki kedua jenis aglutinin, yaitu aglutinin anti-A dan anti-B. Hal ini membuat golongan darah AB dapat menerima transfusi darah dari semua golongan darah lainnya tanpa adanya reaksi aglutinasi.
