1 SISTEM TRACTUS DIGESTIVUS

2 PENGERTIAN Sistem Pencernaan Makanan adalah suatu sistem yang mempelajari tentang Proses terjadinya pencernaan makanan yang masuk kedalam tubuh Manusia mulai dari Cavum Oris sampai sisa hasil pencernaan dikeluarkan dari tubuh melalui Anus, melingkupi Struktur dan Fungsinya.

14 INDERA LIDAH Lidah Lidah berfungsi sebagai indera pengecap
Indera pengecap tersebut terletak pada bagian permukaan atas terbagi menjadi beberapa daerah yang peka terhadap rasa yang berbeda-beda (manis, pahit, asin dan asam) Permukaan lidah juga dapat merasakan panas, dingin, kasar, halus dan nyeri.

16 LIVER- HATI Fungsi hati Hati melakukan lebih dari 500 fungsi, termasuk: • Pengolahan nutrisi dari makanan; • Menyimpan energi; • Menyaring bahan kimia beracun dan bakteri dari tubuh; • Pengolahan ALKOHOL; • Memproduksi protein tertentu dan LEMAK, termasuk kolesterol), * mengendalikan metabolisme • Menyimpan BESI ; • Membuat vitamin tertentu, termasuk Vitamin A; • Membantu pembekuan darah dan • pengolahan obat-obatan.

30 Respiratory pigments increase the oxygen-carrying capacity of the blood. Humans have the red-colored pigment hemoglobin as their respiratory pigment. Hemoglobin increases the oxygen-carrying capacity of the blood between 65 and 70 times. Each red blood cell has about 250 million hemoglobin molecules, and each milliliter of blood contains 1.25 X 1015 hemoglobin molecules. Oxygen concentration in cells is low (when leaving the lungs blood is 97% saturated with oxygen), so oxygen diffuses from the blood to the cells when it reaches the capillaries.

33 Carbon dioxide concentration in metabolically active cells is much greater than in capillaries, so carbon dioxide diffuses from the cells into the capillaries. Water in the blood combines with carbon dioxide to form bicarbonate. This removes the carbon dioxide from the blood so diffusion of even more carbon dioxide from the cells into the capillaries continues yet still manages to "package" the carbon dioxide for eventual passage out of the body. In the alveoli capillaries, bicarbonate combines with a hydrogen ion (proton) to form carbonic acid, which breaks down into carbon dioxide and water. The carbon dioxide then diffuses into the alveoli and out of the body with the next exhalation.

35 Suplai Darah ke Ginjal ATRIUM Sinistra  Ventricle Sinistra  Aorta Thoracalis  Aorta Abdominalis  Arteri Renalis

36 Tipe-Tipe Nefron 1. Nefron Kortikal Terletak di bagian korteks ginjal
Sebagian besar nefron termasuk ke dalam tipe ini.

37 2. Nefron Juxtamedular Terletak di bagian medula ginjal
