The right ventricles pumps blood to the lungs through the pulmonary veins this is typically colored blue even through it carries blood away from the heart.
The blood vessels which includes the both inferior and Superior vena cava. These are bring blood from the body to the right atrium.Then pulmonary artery carries that blood from the right ventricles to the lungs . The oxygenated blood is brought back to heart by the pulmonary veins which enter the left artery atrium.
The deoxygenated blood return from the body to the right artium and form there enters the right ventricles which pumps it to the lungs. The right atrium received.

Answer:
Krebs cycle and electron transport chain
Explanation:
Energy in form of ATP, which is needed by all living cells, is produced from a cell process called CELLULAR RESPIRATION. Cellular respiration is composed of three other processes depending on the availability of oxygen: glycolysis, Krebs cycle and electron transport chain.
Overall, glycolysis which takes place in the cytoplasm produces 2 molecules of ATP while the Krebs cycle and electron transport chain (ETC) produces a collective accumulation of 34 ATP molecules.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder).[1] In this system, the process of digestion has many stages, the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.
Chewing, in which food is mixed with saliva begins the process of digestion. This produces a bolus which can be swallowed down the esophagus and into the stomach. Here it is mixed with gastric juice until it passes into the duodenum, where it is mixed with a number of enzymes produced by the pancreas. Saliva also contains a catalyticenzyme called amylase which starts to act on food in the mouth. Another digestive enzyme called lingual lipase is secreted by some of the lingual papillae on the tongue and also from serous glands in the main salivary glands. Digestion is helped by the mastication of food by the teeth and also by the muscular actions of peristalsis and segmentation contractions. Gastric juice in the stomach is essential for the continuation of digestion as is the production of mucus in the stomach.
Peristalsis is the rhythmic contraction of muscles that begins in the esophagus and continues along the wall of the stomach and the rest of the gastrointestinal tract. This initially results in the production of chyme which when fully broken down in the small intestine is absorbed as chyle into the lymphatic system. Most of the digestion of food takes place in the small intestine. Water and some minerals are reabsorbed back into the blood in the colon of the large intestine. The waste products of digestion (faeces) are defecated from the anus via the <span>rectum</span>
