Bones of the Human Skeleton (page 216) The human skeleton, like other vertebrate skeletons, is divided into axial and appendicular components. The is the main longitudinal portion. includes the bones of the appendages and their supportive pectoral and pelvic girdles. EX-4) List all axial bones; List all appendicular bones: Vertebrate Muscles (page 220) Muscle contraction accounts for an animal's ability to respond quickly to outside stimuli. Muscles along with " because they carry out the orders of the nervous system. are called " muscular tissue is The three types of vertebrate muscles are smooth, cardiac, and skeletal. not under conscious control and is predominantly found in the walls of hollow organs, such as the bladder, blood vessels, uterus, and digestive tract. contains alternating light and dark bands, and is not under conscious control. tissue is under conscious control and has striation (alternating light and dark bands.). The cells that make up muscular tissue are called " muscular tissue, found in the heart, is striated muscular EX-5) Remember smooth muscle, cardiac muscle, and skeletal muscle on microscope and Lab manual, based on the Figs. 32.7, 32.8, and 32.9 EX-6) Contrction of muscular fibers (page 226): Electron microscopy has shown that striations in skeletal muscle are due to the placement of myosin and actin filaments. During contraction, units of the muscle called filaments, and filaments slide past shorten. ATP serves as the immediate energy source for are cofactors for the contraction.

Answer 1

Cardiovascular system:

Ex: 2 - ans: Left ventricle is more muscular as compared to right ventricle because it pumps more blood.

Respiratory system:

the lungs contain bronchioles , air sacs surrounded by cappilaries. Here gas exchange by alveoli brings oxygen into blood and takes CO2 out of the blood.

Digestive system:

Digestive system contains organs in which food is ingested, secreted, migrated and prepared for elimination.

The trace path of food is: mouth, pharynx, eosophagous, stomach, small intestine, large intestine, anus.

The intestine processes food and absorbs nurient molecules.

Urinary system:

Kidneys( which produces urine),ureter ( which passes urine to) the urinary bladder ( where urine is stored). urethra which transports urine to outside.

Nervous system:

vertebrate nervous system consists of Brain , Spinal cord and nerves.
