Blood Circulation Process

Guys, do a little research with me! Put the palm of your hand on your chest. Do you feel something beating? Yes. It is your heart. We have known that heart pumps to produce fresh blood for allbody tissues. However, do you know how heart pumps blood and circulate it to all body tissues.

As we talk, the heart ejects oxygen rich blood under high pressure out of the heart’s main pumping chamber, the left ventricle, through the largest artery, the aorta. Smaller arteries branch off from the aorta, leadinng to various parts of the body. These smaller arteries in turn branch out into even smaller arteries, called arterioles.

Capillaries have extremely thin walls that permit dissolved oxygen and nutrients from the blood to diffuse across to a fluid, known as interstitial fluid that fills the gaps between the cells of tissues or organs. The dissolved oxygen and nutrients then enter the cells from the interstitial fluid by diffusion across the cell membranes. In this way, the blood delivers nutrients and removes wastes without leaving the capillary tube.

After delivering oxygen to tissues, the deoxygenated blood an capillaries then starts the return trip to the heart.

Terjemahan :

Teman, lakukan sedikit riset dengan saya! Letakkan telapak tanganmu di dadamu. Apakah kamu merasakan sesuatu berdetak? Ya. Ini adalah jantungmu. Kita sudah tahu bahwa jantung memompa untuk memproduksi darah segar untuk semua jaringan tubuh. Namun,apakah kau tahu bagaimana jantung memompa darah dan mengedarkannya ke seluruh jaringan tubuh?

Seperti yang kita bicarakan, jantung menyemprotkan darah yang kaya oksigen dengan tekanan tinggi dari ruang utama jantung yaitu, serambi kiri terus ke pembuluh nadi terbesar yaitu aorta. Pembuluh nadi terkecil bercabang dari aorta menuju ke segala bagian tubuh. Pembuluh nadi terkecil ini bercabang menuju yang lebih kecil yang disebut arterioles.

Kapiler mempunyai dinding yang sangat tipis yang memungkinkan oksigen dan nutrisi yang larut dari darah berdifusi menyebrang cairan sela yang mengisi celah diantara sel-sel jaringan atau organ. Oksigen dan nutrisi yang larut memasuki sel dari cairan sela dengan cara penyebaran ke membran sel. Dengan jalan ini, darah mengantarkan nutrisi dan zat sisa tanpa meninggalkan pembuluh kapiler.

Setelah mengantarkan olsigen ke seluruh tubuh darah yang tak mempunyai oksigen dalam kapiler lalu kembali ke kapiler.
