Inside the Torso. The body's functions are conducted by organs. Each organ is a recognizable structure (for example, the heart, lungs, liver, eyes, and stomach) that performs specific functions. An organ is made of several types of tissue and therefore several types of cells (see Cells). For example, the heart (see Heart) contains muscle tissue that contracts to pump blood, fibrous tissue that makes up the heart valves, and special cells that maintain the rate and rhythm of heartbeats.
The muscles of our lungs, stomach, and intestines are made of smooth muscle tissue. Cardiac muscle tissue is the third type of muscle tissue. Cardiac muscle tissue makes our hearts. Organs are groups of tissues that work together to do a job.Our skin is made of hair tissue, oil and sweat gland tissues, nerve tissue, blood tissue, and many other tissues to make the organ called skin.Our eyes are made of nerve tissue, blood vessel tissue, muscle tissue, lens tissue, pupil tissue, and many more types of tissue to make the organ called eyes.he muscles of our lungs, stomach, and intestines are made of smooth muscle tissue. Cardiac muscle tissue is the third type of muscle tissue. Cardiac muscle tissue makes our hearts. Organs are groups of tissues that work together to do a job.
