Skeletal && Digestive System

SKELETAL:

The bones of the tiger's front legs are strong and dense to support the large musculature used for taking down large prey.

The bones in each of the tiger's feet are tightly connected by ligaments allowing them to buffer the impact of landing from running, pouncing and leaping when after prey.

The skull of the tiger is stout and round which provides more support for their jaws, which are very powerful.

Their jaw muscles are attacked to a ridge that lays on top of the skull. The ridge is called the sagittal crest. The function of these muscles is to crush down rapidly with much force on their prey.

Tigers have a small collarbone. This allows then to take greater strides when running because it allows a wider range of movement of the shoulderblade.

DIGESTIVE:

Their large canines grab and kill prey, scissors-like molars slice flesh and small incisors scrape meat from bones.

Like all cats, tigers have a simple digestive system designed to process meat so that the nutrients can be absorbed into the bloodstream and waste ejected fast through a straight tube rather than long intestines.

Reproduction

Female tigers become sexually mature at age 3 or 4.
Male tigers become sexually mature at age 4 to 5.

Estrus cycle
A female tiger may enter estrus (the time when a female is receptive and capable of conceiving young) every 3 to 8 weeks, and her receptivity lasts 3 to 6 days.

In tropical climates, females may come into estrus throughout the year, though mating seems occur more during the coolest months (November to April).

In temperate regions, females enter estrus and mate only during the winter months.

When ready to mate, the female lion roars until a male responds.

Tigers reproduce sexually.
Both male and female tigers may have several mates over their lifetime.

Circulatory System

The tiger’s heart has 4 chambers.
There are 2 different heart chambers, one being for moving the blood and the other for recieving the blood.

The right atrium pumps blood to the right ventricle, and the left atrium pumps blood into the left ventricle.

The heart of a tiger weights approximately 2kgs.

A tiger’s heart rate is about 70 – 80 beats a min.
