one of the many purposes of the small intestine is to extract the nutrients and or digestive juices from what enters it
Cardiac output (CO) is determined by the heart rate (HR) and the volume of blood pumped by each beat (stroke volume - SV). Mathematically, cardiac output can be represented by the equation: CO = HR x SV As such, if total cardiac output falls as a result of decreased stroke volume, the heart rate can increase to keep the total cardiac output normal, to a certain extent. Stroke volume is more complicated; it is determined by many different factors, including preload, afterload, competence of the atrioventricular valves, ventricular cavity size, and the strength of the squeeze of the cardiac muscle, amongst others. Any change in one of these factors requires a compensation in one or more of the others to maintain cardiac output.
Like humans, kangaroos have a small intestine and a large intestine.
The small intestine and is involved in the process of digestion. nutrients such as carbohydrates, protein, fats, and many vitamins and minerals are absorbed by your small intestine. the small intestine stretches from your stomach to the beginning of your large intestine. it is broken in to three distinct zones - the duodenum, the jejunum, and the ilium

The cardiac muscles are present in your heart. The smooth muscle are present in your intestine and other many hollow tubes in your body. Both of them are involuntary type of muscles.
Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
small intestine ha many projections called villi they are shaped like fingers and they absorb nutrients from the food and passes it to the large intestine for further absorption if any.

Amylase, protease and lipase are secreted from the pancreas into the small intestine. Sucrose, maltase, lactase from the wall of the intestine are also used to complete digestion.
